POLYPROPYLENE IN-REACTOR ALLOY COMPOSITION AND PREPARATION METHOD THEREFOR

Title:

POLYPROPYLENE IN-REACTOR ALLOY COMPOSITION AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2016/074244

Kind Code:

A1

Abstract:

Provided are a polypropylene in-reactor alloy composition and a preparation method therefor. The preparation method for the polypropylene in-reactor alloy composition comprises propylene undergoing a polymerisation reaction in the presence of an olefin polymerisation catalyst component and a cocatalyst, then ethylene and an α-olefin being passed through the polymerisation reaction system and the polymerisation reaction being continued, the olefin polymerisation catalyst component containing halloysite, a transition metal component and a non-transition metal component. When the transition metal component is a titanium tetrahalide and/or a titanium alkoxide, the non-transition metal component is a magnesium-containing compound. When the transition metal component is a metallocene compound and/or a non-metallocene compound, the non-transition metal component is an aluminium-containing compound. When the transition metal component is mixture of a titanium tetrahalide and/or a titanium alkoxide and a metallocene compound and/or a non-metallocene compound, the non-transition metal component is a mixture of a magnesium-containing compound and an aluminium-containing compound. The polypropylene in-reactor alloy composition has a relatively high melt strength and relatively high mechanical properties.
